The incorporation of the extract of an Amazonian plant Copaifera officinalis within the matrix of films based on Peruvian bitter potato starch and potato starch (PS) blended with chitosan or soy protein isolate enhances their physicochemical, antioxidant, and degradation characteristics as compared with those of a neat PS?based film.AbstractFilms based on bitter potato starch (BPS) and its blends with chitosan (BPS?Ch) or soy protein isolate (BPS?SPI) loaded with copaiba leaf extract (E) are prepared via the casting method. The physical–mechanical and antioxidant properties of the as?prepared films are compared with those of a control. Moreover, the half?maximal degradation (t50) of the prepared films is calculated by fitting the Hill model to disintegrability kinetic data. Among the analyzed films, BPS?Ch?E exhibits the lowest (p?
